    Description

      Using "lfs mirror split --destroy" is not a very obvious way to remove mirrors from a file. It would be useful to add "lfs mirror delete" (with a man page, of course) to do the same thing.

      The lfs mirror split command currently requires specifying an explicit mirror ID, but it would be more useful to allow lfs mirror delete to directly use lfs getstripe options like --comp-flags=prefer or --pool=flash to remove replicas.

            It would also be useful to add a "lfs mirror flags {--comp-id=N|--pool} --comp-flags={prefer,nosync} <file> ..." command to set the flags on a specific mirror, which is the same as the "lfs setstripe --comp-flags" command that already exists, but is not easily found.
